Zahran et al. (2010) measured the lead concentration of blood (in ug/dl) of children living in the 46 areas both before and after the hurricanes. The ratio of blood lead concentration after the hurricanes to that before the hurricanes is given below. This ratio has an approximately normal distribution. A ratio of 1.0 indicates no change. 0.67, 0.57, 0.88, 0.95, 0.60, 0.98, 0.64, 0.48, 0.26, 0.77, 0.87, 0.34, 0.56, 0.88, 0.77, 0.67, 0.59, 0.56, 0.54, 0.64, 0.90, 0.00, 0.53, 0.63, 0.57, 0.70, 0.41, 0.42, 0.69, 0.45, 0.67, 0.50, 0.60, 1.16, 0.33, 0.63, 0.63, 1.00, 1.05, 0.67, 1.00, 1.00, 0.75, 1.00, 1.00, 0.63
